Wez's Shell

Wzsh - Wez's Shell

A unixy interactive shell for Posix and Windows systems

Goals

• Be a convenient interactive shell
• Feel familiar to long-time unix users by using the Bourne syntax
• Have discoverable builtins and help
• Run on Windows without requiring cygwin, msys or wsl

Non-Goals

• I don't want to replace /bin/sh or /bin/bash shebang usage. I don't believe in long shell scripts and I don't think wzsh should try to compete in that space. More information

Implementation Status

In no particular order, except that completed items bubble up to the top:

• - Executes simple commands, pipelines, input/output redirection
• - Parameter substitution ($FOO)
• - Globbing and filename generation
• - Basic job control (ctrl-z to background, bg and fg to manage a backgrounded job)
• - Define and execute functions
• - Conditionals of the form true && echo yes and if/then/else/elif/fi
• - line editor functions that can search and match history (ctrl-R!)
• - persistent history and builtins for examining history
• - looping constructs such as for, while, until
• - case/esac matching construct
• - tab completion of commands, filesystem entries
• - command substitution $(date)
